Preventing Rot on Your Flat Roof

Preventing Rot on Your Flat Roof

Minor roofing issues that are not addressed will eventually worsen, potentially causing serious damage, like roof rot. This issue often requires roof replacement, a costly endeavor.

What Causes a Flat Roof to Rot?

Rot is almost always caused by moisture buildup, which is usually a result of poor ventilation in the roofing system. If you have wooden foundations supporting your roof, then your system is particularly vulnerable to rot. Wood that is exposed to moisture for prolonged periods will eventually rot and release fine gray strands of microscopic fungus into the surrounding fiber. 

Roof rot can also break down other roofing materials, potentially compromising the roof deck as well as the sheathing. Do not ignore this problem if this is happening to your commercial roofing system. If not addressed properly, rot can grow as much as 10 feet in a year, which can seriously deteriorate the roof’s internal structure.

How to Spot for Signs of Roof Rot

Fortunately, it’s easy to check whether your flat commercial roof has roof rot. One telltale sign is ponding on some sections of the roof. Poor drainage from clogged gutters as well as defective interior drains can also cause roof rot. Check if you have damaged roofing membranes, since this allows water to penetrate through the outer roofing structure. 

Preventive Measures Against Roof Rot 

It’s not hard to avoid roof rot. All you need to do is to have a professional roof inspection at least once a year. You should also make sure to remove roof debris as soon as possible. Debris that collects on your roof can obstruct water flow, leading to ponding. If you see any cracks or visible signs of deterioration on your roof, have it repaired as soon as possible.
